Article Synopsis
- Hemostatic agents are commonly used in dental procedures to control bleeding, but they can negatively impact the bonding of resin composites to dentin, making their removal before bonding important.
- The study involved 90 premolar teeth divided into groups treated with either no hemostatic agent, ferric sulfate, or aluminum chloride, with cleanup methods including water, phosphoric acid, katana cleaner, and air abrasion.
- Results showed that the type of hemostatic agent and cleansing method significantly affected bond strength, with phosphoric acid yielding the best results and ferric sulfate showing the lowest bond strength.
Effect of Light Curing Distance on Microhardness Profiles of Bulk-Fill Resin Composites.
Polymers (Basel)
January 2022
Bulk-fill (BF) dental resin composites are made to be polymerized in increments of up to 5 mm rather than the 2 mm increment recommended for conventional composites. This project aimed to determine microhardness (MH) profiles of BF resin composites at different depths and varying light cure (LC) distances from the light source in an attempt to mimic varying clinical situations. Forty-eight cylindrical specimens (4 mm diameter and 6 mm height) were prepared from 3 BF composites: Tetric N-Ceram Bulk-Fill (TBF), Filtek One Bulk-Fill (FBF), and Sonic-Fill 2 (SF2).

Objective: The objective of the study is to investigate the effect of infection control barrier (ICB) and curing time on irradiance of light cure units (LCUs).
Methods: Irradiance (mW/cm) of the LCUs at a government dental school were recorded with and without ICB at 0 (T), 10 (T), and 20 (T) seconds using a digital radiometer. Data were analyzed using IBM SPSS Statistics Version 17 for Windows software for the analysis of variance and Bonferroni methods at 0.
